Segmentation fault launcher and AmnesiaAMFP.bin.x86_64

**Joseph Curwen** · 09-11-2013, 09:40 PM

I'm running Ubuntu 12.04 on an Acer laptop with Intel/Nvidia hybird graphics card. To run programs on the nvidia card I use optirun.

I installed AAMFP to my /home directory, so probably no permission problems.

Spoiler below!

Trying to run without the launcher:

Code: (Select All)

me@abulafia:~/Games/AmnesiaAMFP$ ./AmnesiaAMFP.bin.x86_64 

Segmentation fault

The hpl.log contains:

Code: (Select All)

Version 1.20

Any suggestions?

**Ideka** · 09-17-2013, 04:05 AM

Is it only the game that segfaults when you start it, or does the launcher segfault too?

Not sure if it'd help, but maybe try a stack trace?

Code: (Select All)

$ strace -o some_file_name ./AmnesiaAMFP.bin.x86_64

No idea what optirun is, but you might as well try:

Code: (Select All)

$ strace -o some_file_name optirun ./AmnesiaAMFP.bin.x86_64

Also in case that doesn't output any useful information, perhaps try this:

Code: (Select All)

$ optirun strace -o some_file_name ./AmnesiaAMFP.bin.x86_64

Please post the hpl.log from ~/.frictionalgames/Amnesia/Pig/

**Joseph Curwen** · 09-17-2013, 09:09 AM

Both Amnesia and the launcher segfault (see my first post).
Optirun is a program that runs other programs on the nvidia graphics card instead of the lower spec intel card. See here: https://wiki.ubuntu.com/Bumblebee

My hpl.log:

Code: (Select All)

Version 1.20

Code: (Select All)

$ strace -o strace_aampf.txt ./AmnesiaAMFP.bin.x86_64

Do you need this?

Anyway, I also tried:

Are you sure the launcher is segfaulting though? If it segfaults after you click "Launch game", the launcher is probably working properly.

See if you can post your stack trace with pastebin: http://pastebin.com/

I do not even get a Window from the launcher. It just segfaults in the console.

open("/home/me/Games/AmnesiaAMFP/lib64/tls/x86_64/libXext.so.6", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)

So it looks as if it can not open any of the libraries in lib64 in the game folder. But ldd shows these libs as loaded. Strange.

That's a red herring.. Because the Amnesia binaries have a runpath set on them the linker will try to load libs from the lib64 directory FIRST. Then it will search the standard paths. as you'll notice it checks the system paths and loads the libs from there right after.

Can you try running the game through GDB? and when it "Crashes" do a

thread apply all bt

in GDB and copy/paste the output.

the straces you had looked fine up until it crashed.. it was just going along loading up SDL init bits (finding the X libs etc..) but it bombs somewhere just after the init. a backtrace (bt) would help in identifying what the game is trying to initialize. As this appears to have nothing todo with bumblebee.

well.. then it's crashing while initializing the video subsystem Sad

What is your LANG env variable set to?

echo $LANG

My $LANG is set to: eo.UTF-8
(This is Esperanto)

OK, I found it.

If you set your LANG=C then both the Game and the Launcher run.

Thank you very much for your help, this solution really was not obvious to me.

Just out of curiosity: Why did you suspect the $LANG env and why does it crash when it does not recognize its contents? This clearly is not intended behaviour, is it?
